Three questions if I may: 1. Can AGL advise on the sizes of the larger batteries contemplated and to be realeased at a later date (i.e. how much larger than 7.2 KWh)2. What is AGL thinking around providing storage for customers with 3 phase requirements?3. Is AGL wedded to lithium ion or other lithium derivatives, or for example flow batteries for commercial / industrial customers with larger loads?
